The former America's Top Model champ, now married to Brady Bunch actor, Christopher Knight, had surgery to fix breasts that were different sizes - and writes about the event in detail for the upcoming issue of Us Weekly.

"When I woke up, I was screaming in pain and they shot me up with morphine," she writes. "Later I was prescribed Percocet and Valium, but I think because I was addicted to cocaine and heroin as a teenager, they didn't really affect me."
